It's A Cellular Life!

You and I, we’re made up of cells – all sorts of them. Cells are the structural and functional units of all living organisms. The size of one of our cells can be a range between 5 to 100 microns in diameter, or across its width. (As examples of these sizes, consider this: 500 microns is about the size of a granule of table salt and 100 microns is the thickness of a human hair.) Though very different in their specialized functions, the cells from which we are made are all derived from one cell (the fertilized oocyte) and are all more similar in their basic operations than they are dissimilar. Think about that. Think of how different your eye is from your skin and how different those cells must be compared to the cells in your brain, it’s really amazing to know that they all came from one cell. The workings of these cells are intricate, intriguing, and still not completely understood. Every day, more discoveries are made about how our bodies do what they do through their cellula...
